Vedclass · Answer

(A) $2 NaNO_3 \longrightarrow 2 NaNO_2 + O_2$ ($Na_2O$ is not formed).$4 LiNO_3 \longrightarrow 2 Li_2O 	ext{ (basic)} + 4 NO_2 	ext{ (acidic)} + O_2$.$2 Be(NO_3)_2 \longrightarrow 2 BeO 	ext{ (amphoteric)} + 4 NO_2 	ext{ (acidic)} + O_2$.$2 Ca(NO_3)_2 \longrightarrow 2 CaO 	ext{ (basic)} + 4 NO_2 	ext{ (acidic)} + O_2$.$NO_2$ is an acidic oxide. $Li_2O$ and $CaO$ are basic oxides. $BeO$ is amphoteric. Thus,$Ca(NO_3)_2$ and $LiNO_3$ produce both acidic and basic oxides along with $O_2$.

Which of the following,on thermal decomposition,form both acidic and basic oxides along with $O_2$?
$(i)$ $NaNO_3$ $(ii)$ $Ca(NO_3)_2$ $(iii)$ $Be(NO_3)_2$ $(iv)$ $LiNO_3$
